The 3.2-liter V6 engine of the Opel Y32SE or LA3 was produced in England from 2001 to 2005 and was installed on the Omega, Signum and Vectra C, and during the transition to Euro 4 it was already under the Z32SE index. There is a compressor modification of this engine from Irmscher with a power of 300 hp, 370 Nm.
The Y line includes: Y26SE, Y32SE.

The engine was installed on:

- Opel Signum A (Z03)* in 2003 – 2005;
- Opel Vectra C (Z02)* in 2002 – 2005.
* – under the index Z32SE.
Disadvantages of the Y32SE engine
- Quite a lot of problems for engines of this series are caused by an unreliable crankcase ventilation system.
- Another weak point of the motors of this series is the ever-leaking heat exchanger.
- Closer to 250,000 km, the performance of the oil pump decreases, which is fraught with overturning.
- Keep an eye on the cooling system; if it overheats, it will quickly blow through the cylinder head gaskets.
- Ignition coils, lambda probes and crankshaft position sensor are also often replaced.
